shuttle SN41G2 tv out

[dindin57]

Hi there. I got a shuttle with embeded geforce4MX inthere.
I managed to run xorg or xfree4.3 shiped with debian sid.

I'm allready using it everyday with no crash (just one using composite extension which is far from stable, and, btw, slow).

I try setup my tv-ou.... everything I can get is a blankscreen.

here is a part of my xorg.conf :

Section "Device"
Identifier "Generic Video Card"
Driver "nvidia"
Option "ConnectedMonitor" "CRT,TV"
Option "TwinView" "1"
Option "TwinViewOrientation" "Clone"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60-60"
Option "TVStandard" "PAL-N"
Option "TVOutFormat" "COMPOSITE"
Option "MetaModes" "1280x1024,640x480"
Option "RenderAccel" "true"
Option "NvAGP" "1"
EndSection

My calbe is ok since i tested it on another box running and got tv-out working.

nvidia NVIDIA-Linux-x86-1.0-6629-pkg1.run

anyone got some clues ?

thanks in advance !
